Solid Single-Crystal Laboratory-GrownDiamond Ring
THE FUTURE OF TRUE LUXURY.
-No metal. No setting.
Just one flawless laboratory-grown crystal sculpted into a ring. A rare marvel of cutting-edge craftsmanship and pure elegance.
A Milestone in High Jewelry Innovation
The Rarity of a Diamond Ring Carved from a Single Crystal
In the world of fine jewelry, few creations are as rare or as technically ambitious as a ring carved entirely from a single diamond crystal. Once considered nearly impossible, advances in laboratory-grown diamond technology have brought this extraordinary vision to life. A recent evaluation by the GIA New York laboratory unveiled a remarkable achievement: a solid, faceted ring fashioned from a single-crystal CVD-grown diamond.
Weighing 4.04 carats, this exceptional ring is sculpted entirely from one continuous diamond crystal. The band measures approximately 3.03 mm in thickness, with an inner diameter of 16.35-16.40 mm and an outer diameter of 20.32-20.40 mm, reflecting a level of precision rarely seen in diamond manufacturing. The piece was created by Dutch Diamond Technologies, in collaboration with the historic Belgian jewelry house Heursel, established in 1745.
From CVD Diamond Plate to Sculptural Masterpiece
The ring originated from an 8.54-carat single-crystal diamond plate grown using chemical vapor deposition (CVD). Advanced laser-cutting techniques were employed to shape the crystal into a nearly flawless circular form. Digital imaging analysis confirmed the remarkable accuracy of both the inner and outer circumferences, demonstrating exceptional control over material removal at the microscopic level.
Crafting a solid diamond ring from a single crystal is among the most challenging processes in modern gem cutting. Even minimal imbalance in internal strain or microscopic fractures can cause catastrophic failure. For this reason, production timelines are extensive and unforgiving. In this case, the creation process spanned more than six months, involving approximately 1,131 hours of processing in Kuik, Netherlands, followed by an additional 751 hours of meticulous polishing in Belgium.
Advanced Gemological Analysis and Diamond Type
Spectroscopic examination identified the diamond as Type IIa, indicating an absence of detectable nitrogen, an attribute associated with the highest purity diamonds. No hydrogen-related absorption peaks were detected at 3107 or 3123 cm⁻¹. Photoluminescence spectroscopy revealed complex vacancy-related defects consistent with advanced CVD growth techniques.
A strong emission from the silicon-vacancy (SiV⁻) defect was observed using 633 nm laser excitation, a hallmark feature of CVD-grown diamonds. Importantly, analysis confirmed that the diamond had not undergone any post-growth treatment. The ring exhibited exceptionally low levels of nitrogen-related defects, with no detectable H3, NV centers, 468 nm peak, or the 596/597 nm doublet-features sometimes observed in other synthetic diamonds.
Optical Beauty Revealed Through Precision Imaging
Microscopic observation under cross-polarized light revealed strong birefringence, forming an unusual radial strain pattern that reflects unique and highly controlled growth conditions. Further imaging using Diamond View technology under deep ultraviolet illumination confirmed these characteristics, revealing blue fluorescence without the green hues associated with post-growth treatments.
These optical features distinguish the ring from conventional laboratory-grown diamonds currently available on the market, underscoring its singular origin and craftsmanship.
GIA Grading and Finish
The ring was examined and graded by GIA, receiving a VVS2 clarity grade. The clarity grade reflects the presence of minute, dark non-diamond carbon pinpoints-growth remnants typical of CVD-grown diamonds. The polish was assessed as Good, as polishing the interior surface of the ring limited further refinement. Due to its continuous circular form, symmetry was deemed not applicable, though the ring’s shape is notably precise. The diamond displays a high color grade on the GIA scale and is laser-inscribed “Laboratory-Grown” on a side facet.
A Defining Moment for Laboratory-Grown High Jewelry
This solid single-crystal laboratory-grown diamond ring stands as a powerful symbol of innovation, artistry, and the future of high jewelry. Its size, purity, and structural complexity demonstrate how far CVD diamond technology has evolved-and how it is reshaping traditional concepts of luxury.
Notably, this marks the first time a GIA laboratory has examined a colorless ring crafted entirely from a laboratory-grown diamond, establishing a new benchmark in contemporary fine jewelry design.
